via my cousin, around fourth grade:
Three women, a blonde, a brunette and a redhead rob a bank. As they are escaping from the police, they run into an alleyway and hide in a bunch of sacks, just before they are seen.
The blonde hides in a sack labelled “puppies.” As the police walk by, they kick the sack and the blonde says “woof! woof!”
The police keep walking.
The brunette hides in a sack labelled “kittens.” As the police walk by, they kick the sack and the brunette says “meow! meow!”
The police keep walking.
The redhead hides in a sack labelled “potatoes.” As the police walk by, they kick the sack and the redhead says “potato! potato!”
